Infineon Technologies BCR183WH6327XTSA1

Overview

BCR183WH6327XTSA1 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 10 kΩ), designed for switching, inverting, interface, and driver circuits in automotive and industrial control systems. It features V_CEO = 50 V, I_C = 100 mA, V_CE(sat) ≤ 0.3 V at I_C = 10 mA/I_B = 0.5 mA, h_FE ≥ 30, and AEC-Q101 qualification.

For engineers reviewing the BCR183WH6327XTSA1 datasheet, BCR183WH6327XTSA1 pinout, BCR183WH6327XTSA1 application, or BCR183WH6327XTSA1 equivalent, key selection criteria include built-in resistor matching, thermal resistance (R_thJS ≤ 105 K/W), SC74 package compatibility, and guaranteed operation up to T_j = 150 °C in automotive-grade environments.

Technical Context

This device integrates two matched PNP transistors in a single SC74 (SOT-363) package with isolated die and symmetrical pinout. Its internal R1/R2 ratio (0.9–1.1) ensures consistent turn-on/off thresholds across temperature (−40 °C to +125 °C) and supports reliable logic-level interfacing without external bias components.

The transistor operates in common-emitter configuration with defined DC characteristics: V_(BR)CEO = 50 V, I_CBO ≤ 100 nA, and I_EBO ≤ 0.75 mA. AC performance includes f_T = 200 MHz and C_cb = 3 pF, enabling use in medium-speed digital switching up to ~10 MHz edge rates.

FAQ

What is the maximum operating junction temperature for BCR183WH6327XTSA1?

The absolute maximum junction temperature is 150 °C, validated per AEC-Q101 stress testing. Derated power dissipation begins at case temperature >124 °C, where P_tot linearly decreases from 250 mW to zero at 150 °C. This enables sustained operation in under-hood automotive environments and sealed industrial enclosures without active cooling.

Can BCR183WH6327XTSA1 be used in high-frequency switching applications?

Yes-its 200 MHz transition frequency (f_T) and 3 pF collector-base capacitance support clean switching up to ~10 MHz square-wave edges. However, it is not intended for RF amplification or GHz-range operation. For PWM-driven LED dimming or logic-level signal routing below 20 MHz, it delivers low propagation delay and minimal overshoot due to controlled internal resistor damping.

How does the built-in resistor network affect base drive requirements?

The integrated R1 (10 kΩ) and R2 (10 kΩ) eliminate external base resistors and set a fixed current gain ratio. With 3.3 V logic drive, base current is ~0.33 mA, sufficient to saturate the transistor at I_C ≤ 10 mA. This simplifies layout, improves ESD immunity, and ensures consistent turn-on behavior across voltage and temperature variations without recalculating bias networks.

Is pin 1 orientation defined in the tape-and-reel packaging?

No-per Infineon's marking layout note, symmetric SC74 packages like BCR183WH6327XTSA1 have no defined Pin 1 orientation in reel. Visual identification relies on the laser-marked "1" or "•" adjacent to Pin 1 on the top surface. Automated placement requires vision-based fiducial alignment or post-placement electrical verification due to rotational ambiguity in reel feed.
